Back to Europe

Hi guys We are back to Europe. - I gave 4 days lecture in cameroon and we got a lot of fun even if the room was fully packed. From 8 to 16h30 with Carambars - Then in Togo I gave one afternoon lecture to University catholic of Lome. - Then Esteban arrived and we gave 4 days lecture from 8 to 17h in Universtity of Lome. In the future we hope to get another lecture in Lome - probably two. People from Center Togo (Paillard and Sabirou) jumped on pharo and started to teach it just one week after I went there in September and they love it. I hope that they will write a paper for IWST. They hope their students will create software for companies within one or tewo years. People of the university of Togo may be interested to develop software with Pharo. The TinyBlog tutorial went really really well. Thanks Olivier Auverlot for the first version. I'm happy that I push it so much. https://ci.inria.fr/pharo-contribution/job/TinyBlogTutorial/6/artifact/book… I'm adding a REST chapter. Once the tutorial is finished we will translate it in english. I may go back to togo to give a lecture to teachers in May. We will see :) Since our flight was cancelled (yes we woke two time at 3h45 and 1h in the morning) I wrote the following tutorial based on the great lecture esteban did on Voyage. https://ci.inria.fr/pharo-contribution/view/Books/job/PharoBookWorkInProgre… Stef

NativeBoost class>>#isEnabled ?
by Alexandre Bergel Dec. 28, 2015

Dec. 28, 2015

Hi Esteban, The following expression "NativeBoost isEnabledâ raises an error in a Spur image. Would it be difficult to restore the original semantics of this method? Our 3d effort is currently stuck in a pre-spur image.

Here's the thing that gets my goat: I had already acknowledged it was enough for the list and was signing off further comment when Ben decided he really needed to add his two cents. It is unfortunate he did not spend his change in a positive manner but wished to be negative and critical. I was unwilling to let that go by as an implicit restriction on the substance of my posting, into the future. ...and the thread is twice as long. Not my doing. Some things must be challenged. Do you know what I mean, then? Just say no to intellectual coercion. robert On 12/27/2015 11:33 AM, Ben Coman wrote: > Hi Robert, > > I'm glad your found someone on the list to connect to on a spiritual level, > but could you please keep your public posts to technical matters, > (plus keep signatures short and trim old signatures from quoted > responses - which unfortunately threaded email clients like gmail > often hide) > > cheers -ben > > On Mon, Dec 28, 2015 at 2:15 AM, Robert Withers > <robert.w.withers(a)gmail.com> wrote: >> *My apologies...I'll try for #random. :)* >> >> nameste, >> robert >> >> >> -- >> There are five kinds of coloring (kleshas): >> 1) forgetting, or ignorance about the true nature of things (avidya), >> 2) I-ness, individuality, or egoism (asmita), >> 3) attachment or addiction to mental impressions or objects (raga), >> 4) aversion to thought patterns or objects (dvesha), and >> 5) love of these as being life itself, as well as fear of their loss as >> being death. >> (avidya asmita raga dvesha abhinivesha pancha klesha) >> >> >> On 12/27/2015 09:44 AM, Robert Withers wrote: >> >> I was thinking about this on my drive home, more, and I think that I was >> jumping the duck. #new is related to named classes, therefore in the analogy >> of brahma-loka, this is more of a rupa level behavior.

Wait a second here. Let's be clear. In your first paragraph you say no need to feel that I am censored or ostracized, then the second paragraph you censor me. Alright, I ask you all. Which meta-model is acceptable for practical work in my stack? I need a meta-model to describe it, or rahter anyone should be able to skin the meta-model they want and that makes most sense. These consciousness meta-models, or meta-memes, from religious tradition are well-defined models. Is the cellular meta-meme acceptable or is also the Mythic meta-meme? Or are both having no place here? This is Smalltalk to me and my practical use of it. It is directly related to interactive fiction, which was just posted about. I am not trying to be belligerent, nay defend myself from hypocrisy and secure my rights, here. So which is the acceptable meta-model?

Dealing with Class and Metaclass instances when using STON
by Sven Van Caekenberghe Dec. 26, 2015

Dec. 26, 2015

Hi, In STON #bleedingEdge I added the ability to write and read Class and Metaclass instances by using their global name. So, Point will be written as Class[#Point] while Point class will be written as Metaclass[#Point]. This is of course a short-circuit solution for the complex structure that a class actually is, but a reasonable compromise. It is in any case better than not handling these types of instances, which was the case before. === Name: STON-Core-SvenVanCaekenberghe.64 Author: SvenVanCaekenberghe Time: 23 December 2015, 10:50:14.195912 pm UUID: b7ced20a-a7a4-4b0f-8f27-db73231eeecb Ancestors: STON-Core-SvenVanCaekenberghe.63 Added the ability to write and read Class and Metaclass instances using their global name === Name: STON-Tests-SvenVanCaekenberghe.59 Author: SvenVanCaekenberghe Time: 23 December 2015, 10:51:06.830762 pm UUID: 9f684bc1-45e1-4bfa-885b-c56ea178bfca Ancestors: STON-Tests-SvenVanCaekenberghe.58 Added unit test for the ability to write and read Class and Metaclass instances using their global name === Thanks to Norbert Hartl for requesting the feature and for test driving it.

Are Critical Tools Becoming Too Brittle?
by Sean P. DeNigris Dec. 25, 2015

Dec. 25, 2015

I just tried to inspect a domain object and I froze my image and had to force quit. How do I debug this? And, more importantly, when an error is encountered in a critical, basic tool like this, should there be some reasonable bare-bones alternative, like the emergency debugger? Not being able to inspect an object without crashing seems like a pretty crippling situation... ----- Cheers, Sean -- View this message in context: http://forum.world.st/Are-Critical-Tools-Becoming-Too-Brittle-tp4867206.html Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com.

Object graph stream/visitor implementation?
by Denis Kudriashov Dec. 24, 2015

Dec. 24, 2015

Hello. Do we have way to traverse object graph? I want stream which iterate object graph through instance variables with knowledge about path at every step. Maybe Fuel has classes for this ? Best regards, Denis

Examples
by Alexandre Bergel Dec. 24, 2015

Dec. 24, 2015

Hi! Having examples on the class sides imply that examples are not apparent when I do not select the class side of a class. And this is a pityâ¦ Maybe a particular icon can designate classes with examples? Or what about making the <script> pragma works also for instance methods and not only class methods?
